How to Get Rid of the Frown Line Between Your Brows (And What Actually Works)

The frown line between your eyebrows - called the Zornesfalte in German - usually responds best to more than one approach: Botox for the muscle movement that carves it in, filler for any groove still visible at rest, and daily sunscreen plus a retinoid to slow its return. Habitual frowning and squinting make this line appear earlier than the rest of the forehead.

Why does this line show up before the others?

The muscles behind it - the procerus and corrugator supercilii - are small, but they do more repetitions per day than almost any other muscle in the face. Every time you concentrate, squint at a bright screen, or frown without registering it, they pull your brows down and together. Multiply that by years of squinting without sunglasses, reading in bad light, or working in front of a monitor all day, and the line between your brows can set years before a horizontal line higher up on the forehead does, because the frontalis above it only fires when you actually raise your eyebrows - a much rarer expression.

We've covered the anatomy of this specific line in more depth separately - this piece is about what to actually do about it once it's there.

• Squinting without sunglasses fires the corrugator even when you're not frowning on purpose.
• Screen time and close-focus work add thousands of small contractions a year that most people never notice happening.
• Sun exposure accelerates collagen loss in that specific patch of skin, independent of the muscle movement.
• Genetics decide how much elasticity you started with, which is why two people with identical habits don't crease at the same rate.

Put together, that's often enough for this exact line to show up in someone's mid-twenties while a horizontal forehead line waits another decade for the same amount of repetition.

Does Botox actually work for the frown line between your brows?

Yes, and it's the most-researched in-office option for exactly this reason: the procerus and corrugator are small, well-defined muscles that respond predictably to being temporarily relaxed. Botox doesn't fill anything in or add volume - it blocks the nerve signal that tells those muscles to contract, so the repeated fold that's carving the line simply stops happening. For a line that is still mostly dynamic - visible when you frown, gone when your face is at rest - this addresses the actual mechanism rather than working around it. Visible softening usually shows up within three to seven days as the muscle relaxes, which is far faster than sunscreen or a retinoid will ever show a result. Results typically last three to four months before the muscle needs treating again, which is the trade-off for something that isn't permanent.

What if there's still a groove when your face is relaxed?

Once a line has been there long enough, it can leave a visible crease even with a neutral expression - the static stage. Botox stops the muscle from making the fold worse, but it doesn't fill in a groove that has already set into the skin. That's where filler comes in: a hyaluronic acid filler placed under the static line adds volume to physically smooth the groove, which is a different job from relaxing a muscle. The two are often used together - Botox to stop the cause, filler to address what's already there - rather than one replacing the other. Which combination, and in what order, is a decision for whoever is actually looking at your skin, not a blog post. In practice, that usually means waiting two to four weeks after a Botox session before adding filler, since residual swelling can make it hard to judge how much of the groove is actually left once the muscle has properly relaxed.

Can skincare actually prevent it, or is that just marketing?

It helps more at the dynamic stage than once a line is static, but it isn't nothing. Daily sunscreen on that specific fold slows the collagen loss that lets the crease set in permanently - useful because UV damage there is cumulative and largely avoidable. A retinoid, used consistently over months, has reasonable evidence for stimulating new collagen, though results are gradual and modest next to a procedure. Sunglasses outdoors remove one of the most common unconscious triggers - squinting - without you having to think about it. None of this reverses a line that has already become static; it slows how fast a dynamic one gets there. Consciously relaxing the brow during screen work - noticing the pull and releasing it - costs nothing and works alongside sunscreen and a retinoid rather than replacing either one.

None of the above is medical advice. Whether Botox, filler, both, or neither makes sense for a specific face is a conversation for a licensed professional, not an article.

Can you see what it would look like smoother before deciding?

LipsUp previews the forehead as a whole on your own selfie, rather than zooming in on just the line between your brows - so think of it as a general picture of a smoother forehead, not a precise preview of this one line in isolation. It still gives you something concrete to compare against before deciding anything: a computer-generated visualization of smoother forehead lines, done entirely on your device, with only the forehead area processed.

Always consult a licensed professional before any cosmetic treatment.
